- This study addresses parental attitudes and concern in relation to universal neonatal hearing screening by otoacoustic emissions (OAE) testing. The parents of 87 children who had participated during the first year of the universal neonatal hearing screening programme at University Hospital, Linkoping, Sweden were included in the study. These children were all tested during this period and later cared for at three well-baby clinics (part of their primary healthcare). A questionnaire was given to the parents during routine medical check-ups at the well-baby clinics when the infants were 5-6 months of age. Ninety-five per cent of parents stated that they had a positive attitude towards neonatal hearing screening, 1% were ambivalent and 4% were negative about it. The parents wanted early detection of hearing loss and the possibility of early intervention. It was also found that screening did not disturb the children. A few parents were anxious due to repeated testing of their children. The information provided in connection with the test was found to be sufficient by 77% of parents, whereas 11% of parents had negative comments about it (e.g. they wanted more information about the otoacoustic emissions technique). The general attitude among parents towards universal neonatal hearing screening was very positive in that they felt reassured by it. The risk of disturbing the parent-child relationship by early screening seems to be small, and could be further minimized by improved information and rapid and effective follow-up.

- OBJECTIVE: To study the development of the bilateral benefit in children using bilateral cochlear implants by measurements of speech recognition and sound localization.DESIGN: Bilateral and unilateral speech recognition in quiet, in multi-source noise, and horizontal sound localization was measured at three occasions during a two-year period, without controlling for age or implant experience. Longitudinal and cross-sectional analyses were performed. Results were compared to cross-sectional data from children with normal hearing.STUDY SAMPLE: Seventy-eight children aged 5.1-11.9 years, with a mean bilateral cochlear implant experience of 3.3 years and a mean age of 7.8 years, at inclusion in the study. Thirty children with normal hearing aged 4.8-9.0 years provided normative data.RESULTS: For children with cochlear implants, bilateral and unilateral speech recognition in quiet was comparable whereas a bilateral benefit for speech recognition in noise and sound localization was found at all three test occasions. Absolute performance was lower than in children with normal hearing. Early bilateral implantation facilitated sound localization.CONCLUSIONS: A bilateral benefit for speech recognition in noise and sound localization continues to exist over time for children with bilateral cochlear implants, but no relative improvement is found after three years of bilateral cochlear implant experience.

- Objective: To compare bilateral and unilateral speech recognition in quiet and in multi-source noise, and horizontal sound localization of low and high frequency sounds in children with bilateral cochlear implants. Design: Bilateral performance was compared to performance of the implanted side with the best monaural speech recognition in quiet result. Parental reports were collected in a questionnaire. Results from the CI children were compared to binaural and monaural performance of normal-hearing peers. Study sample: Sixty-four children aged 5.1-11.9 years who were daily users of bilateral cochlear implants. Thirty normal-hearing children aged 4.8-9.0 years were recruited as controls. Results and Conclusions : Group data showed a statistically significant bilateral speech recognition and sound localization benefit, both behaviorally and in parental reports. The bilateral speech recognition benefit was smaller in quiet than in noise. The majority of subjects localized high and low frequency sounds significantly better than chance using bilateral implants, while localization accuracy was close to chance using unilateral implants. Binaural normal-hearing performance was better than bilateral performance in implanted children across tests, while bilaterally implanted children showed better localization than normal-hearing children under acute monaural conditions.

- Objective: To study the correlation between P1 latency and the results of clinical language tests (Reynell III and TROG-2), the latter were used as they are recommended for follow-up assessments of children with cochlear implants (Cis) by the Swedish National Quality Register for children with hearing impairment.Design: A clinical cohort study.Study sample - Cross-sectional and consecutive sampling of 49 children with CIs coming for clinical follow-up assessment from March 2017 - December 2019.Results: For all children tested, there was a significant negative correlation (Spearman's rho= -0.403, p = 0.011) between hearing age and P1 latency. A significant correlation between P1 latency and the Reynell III result (Spearman's rho = -0.810, p = 0.015) was found. In the TROG-2 group, there was no significant correlation between their P1 latency and their language test results (Spearman's rho -0.239, p = 0.196).Conclusion: This method seems to be feasible and easily accepted. The study was conducted in a heterogeneous group of children that we meet daily in our clinic. The results indicated that P1 latency has a negative correlation with language development among our youngest patients fitted with CIs and might be a clinical tool to assess the maturation of central auditory pathways.

- This study analyses results from the first Swedish UNHS program. It includes over 33 000 measurement files from 14 287 children at two maternity wards. The screening program uses a two-stage TEOAE test procedure. A database was created in MedLog after data transformation in Word and Excel. The coverage rate was 99.1%. Bilateral pass rate after retesting was 97.0%. A unilateral pass criterion would have resulted in 1268 fewer children (9.0% of target group) for retesting and 231 fewer children (1.6% of target group) for diagnostic evaluation. When the first test was performed on the day the child was born, the pass rate was 64.8%, the pass rate increased to 89.2% when testing≥3 days after birth. High coverage rates and pass rates were found to be possible, independent of the number of children born at the maternity ward. Learning curves were observed in the program with improvements distributed over time. Test performance was clearly better when the children were tested day two after birth or later. © 2007 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.

Tidskriftsartikel (refereegranskat)abstract
- This review discusses the need for universal neonatal hearing screening. Historical background is given concerning conventional childhood hearing screening programmes in western countries. Direct studies on the effects of very early habilitation programmes on speech and language development are cited. Measurement of otoacoustic emissions (OAE) as a tool for neonatal hearing screening is presented. The state of neonatal hearing screening programmes in the US and in Europe, particularly in Sweden, is discussed.

- The purpose of the present investigation is to describe how parents experience a delayed identification of their child's hearing impairment. Ten parents of 8 children were interviewed. The impairment was confirmed when the children were between 2 years, and 5 years and 8 months. The results show that the parents and their child pass through a series of distinct phases: Unawareness, Suspicion, Confirmation and Habilitation. After the birth of the child there was first a calm period, which lasted until the possibility of a hearing impairment was suspected. Once the suspicion was raised, a time of much anxiety and frustration ensued. The parents described how defective communication and misunderstanding lead to frequent conflicts with their child. The differing behaviour of the child, in combination with poor language development, initiated referral to audiological assessment and confirmation of the hearing impairment. After confirmation, the parents felt relief but at the same time a sorrow. When hearing aids had been fitted and education in sign language was under way, the child's language and social behaviour improved. Supposedly, the late detection is explained by the combination of an insufficient test method that cannot detect all children with a hearing impairment and, in cases of uncertainty, a tendency to let the child pass rather than 'bringing bad news'. All parents in the present study would have wished to participate in a hearing screening program for new-borns, had the opportunity been present.

Idiopathic Sudden Sensorineural Hearing Loss in Sweden : Diagnostic Protocol and Treatment in Relation to Outcome
- 2009
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Idiopathic Sudden Sensorineural Hearing Loss (ISSNHL) is a rapid loss of hearing caused by damage to the cochlea (inner ear) or auditory nerve. Spontaneous recovery has been seen in 32% - 81%. The incidence of the ISSNHL has been estimated to be between 5 and 20 per 100,000 per year. Different theories (infections, vascular catastrophes, immunologic damage or intracochlear membrane break) about the etiology have resulted in different treatment policies. The effect of therapy is difficult to evaluate for a single physician who sees just a few patients annually.The aim of the present thesis was to analyze the management and treatment of ISSNHL patients in Sweden with regard to outcome.A national database was developed for Sweden with half of all ENT clinics in Sweden participating by submitting a questionnaire for each patient with SSNHL. The questionnaire covered the patient’s background, current disorder, past and family history of different diseases, examinations and treatment. Audiograms at the onset of SSNHL and after three months were requested.All results were analyzed using ordinal logistic regression looking for interactions with hearing recovery and remaining hearing loss as dependent variables. Independent of treatment or no therapy heredity for hearing loss (I, II), older age (I, II) and presence of vertigo (II) was significantly associated with negative outcome. 40% of all patients had an MRI or CT, where 3 – 4% had acoustic neuroma. 24% of patients with ISSNHL who had hematological tests taken had one or more pathological findings. Blood screening varied from simple routine tests to a complete analysis with such tests as HSP70, Anti-Neutrophilic Cytoplasmic Antibodies (ANCA) and Borrelia tests. There was no association between any of these laboratory tests and either hearing improvement or remaining hearing loss evaluating the tests separately (I, II) or after categorization in comparison with those who had normal laboratory findings (II). Patients with hearing loss in the mid-frequency region had significantly better odds for hearing improvement compared to the other three frequency regions (low, high and “flat loss”). Almost 60% of patients with ISSNHL were medically treated, of which nearly 90% got corticosteroids. The medication had no association with either hearing improvement or remaining hearing loss. However, patients who were prescribed rest or sick leave had higher odds for hearing improvement regardless of other treatment. Those patients who did not receive any treatment at all also came significantly later to the ENT clinics than those treated medically and consequently had worse prognosis.Conclusion: There is no standard program for management or treatment of ISSNHL in Sweden. The diagnostic protocol varies. MRI is an underused resource to get specific diagnoses for the condition especially acoustic neuromas. Regardless of pathological findings, treatment is mainly limited to corticosteroids or no medication with no difference in outcome. A randomized placebo controlled study is necessary to evaluate whether there is an effect of corticosteroids on ISSNHL.
